Lighting device having a vivid and dulling light source with controlled duty cycling thereof

Abstract

A lighting device is disclosed operating a vivid source having a first duty cycle and a dulling source with second duty cycle. The vivid source and the dulling source operate at alternating time intervals where the intensity of one wavelength segment or block is emphasized in the vivid source and absent or de-emphasized in the dulling source. The operation provides the user with an emphasis on objects that reflect or absorb the emphasized wavelength segment.
